    hey guys i pulled in my 88 ramcharger in the shop today to start going threw it and getting it ready for snow. it's a cable operated conventional with a new style motor.. first thing i noticed is when my tech raised the plow i put my hands on it and applied a little pressure and the blade stopped raising, the motor kept running and as soon as i let off it came up. i personally think it's a little lazy comong up but i could be wrong? i adjusted the up/down cable and no adjustment made it any better. could the pump be tired? it doesn't bleed off and come down on it's own either. tired motor? any input would be appreciated. thanks, pete

    First thing you want to do is get a pressure gage on it and check the pump output pressure.You want to see 1850 psi. If you could stop it from raising by just leaning on it but the motor continued to run strong, it's a good indication that the pump pressure is low...either from a weak pump or a weak relief valve spring or contamination in the relief valve itself..

    You dont rebuild the gear pump itself. If they're out of spec, you just replace them with a new one.
